Application tiled 1Search 5,1921. Serial llo. lll-"i508,

To all wia-0m t may Concern Y Be it known that l, SAMUEL- Srarrrr, a citizenV of the United States, residing at Atlantic City, in the county of Atlantic and State of New Jersey, have inventedcertain new and useful improvements in Floats, or which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in floats and has relation more particularly to a device ot this general character especially designed and adapted 'tor use in connection with shut-ott valves suoli as are employed in connection with flush tanks, cisterns or the like, and it is an object olf the invention to provide a device ol this general character having novel and iniproved means whereby the collection of water within theinterior of the float proper is substantially prevent-ed.

Another object of the invention is to provide a device of this general character including a tubular buoyant body provided with an opening in its lower wall and which opening is defined by an outstanding sleeve or neck, said sleeve or neck being adapted to extend below the water level of the fluid with which the float proper coacts and Vwhich sleeve or neck is of a length to assure the sealing of the opening in the lower portion of the body without the water entering within said body, so that the maximum of efficiency at all times of the float is assured.

The invention consists in the details of construction and in 'the combination and arrangement of the several parts of my improved tloat whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use,

as will be hereinafter more fully set lorth.

rlhe novel features ot my invention will hereinafter be definitely claimed.`

In order that my invention may be the better understood, l will now proceed to describe the same with reference to the accompanying drawings, wherein: i

Figure l is a view in vertical section taken through a float constructed in accordance with an embodiment of my invention, the coacting valve rod being shown fragmentarily and in elevation;

Figure 2 is a View partly in side elevation and partly in section showing a lloat constructedun Vaccordaime with my invention in applied position and` at the limit of its upwardymovement as created hy the high water level of the luid with which the float coa-cts; and

Figure 3 is a fragmentary view partly in section and partly in elevation showing the lioat at its lowern'iost position within the coacting tank. l

As disclosed in the accompanying drawings, F denotes a tloat constructed in accordance with an embodiment ot my invention and which vtloat is hollow and has its lower wall provided with -an opening l; Theopening l isdeined'by a depending sleeve or tubular neck 2 ol desired length.

While the Atloat- F in its entirely may be ot' any configuration preferred. itis herein disclosed as having its upper portion 8 substantially semispherical in Yterm with its lower portion l in the form oan inverted CII cone with the opening l arranged at the lower orapex portion thereot'.

rlhe side wall ot" the lloa; ably at the junction between tions 3v and fl is provided with :l socket ni which is threaded or otherwise engaged a cap G. rlie cap 6 at its axial center is provided with an outstanding tubular boss 7 in which is adapted to be engaged, as by threads, the outer end portion ot a float rod S of a type now generally employed in connection with the l'eed valves of liush tanks, cisterns or the like.

tuis to be particularly noted that the axial center of the socket 5 and the inserted cap G is angular to the axial center of the float F as continued through the axial center of the sleeve or neck 2. rlhis angular relation is such that the sleeve or neck 2 is slightly closer to the adjacent end of the rod S than is the upper portion ot the tloat F ot' that portion diametrically opposed to the sleeve or neck 2. By this arrangement, while this angular' relation is obtained, the sleeve or neck 2 and the rod 8 are coplanar.

lt is a recognized tact that with hollow ioats now generally in use, water resulting from internal sweating is collected within the interior of the iloat'and in time its eflicie cy is materially affected. It is, theretore, or importance to provide a float wherein this water may be readily drained ont and to construct a Heat it this kind wherein the water With which the ioat coacts does not enter Within the body7 of the float;

rFliese advantageous results are obtained in the device as herein disclosed as the sleeve or neck 2 is of a length, when the float is partially submerged, to seal the opening l Without any of the Water entering Within the body proper of the float. The Water Within the tank will partially enter Within the neck or sleeve 2 to effect the requisite seal and at the same time will place the air Within the body proper ofthe float under slight compression and this in itself results in the float performing its function with greater etliciency.

It is also desirable to have the float F angularly related to the rod 8 as hereinbefore set forth, so that when the float F is at the limit of its upward movement, as is illustrated in Figure 2, said oat, together with the stem or neck 2, will be substantially in a vertical position.

Figure 3 shows the float F in its loWermost position and With'the Water entirely drained 'from the tank. However, should there be a certain amount of Water remaining Within the tank so that the outer open end, of the nec-k or sleeve is at all times sealed, any Water which may be Within the body vproper of the float F may be conveniently drained therefrom by manually lifting` the float F up out of contact with the Water Within the tank.

From the foregoing description it is thought to be obvious that a float'constructed in accordance with my invention is par- 1,465,3vo l r -ticularly Well adapted forv use by reason of fthereof and for this reasonI do not Wish to be understood as 'limiting myself to the precise arrangement and formation of the several parts herein shownV in carrying out my invention in practice except as hereinafter Y claimed.

claim: Y l. VA float of the class described compris- -ing` a hollow body, one portion of the float vbeing Vsubstantially scmispherical and the opposite portion being Vin the forni of an inverted cone, the apex ofthe second portion being provided with an opening, and an outstanding sleeve defining the opening.'

2. A floatV of the class described comprising a hollow body, one portion of the float being substantially semispherical and the opposite portion being in the form of an inverted cone, the apex of the second .portion being 'provided with an opening, an outstanding sleeve deining the opening, the float at the junction of the semispherical and the cone portions being provided with a socket, and a body engaged-Within the socket and adapted for connection. with a float rod or the like.

In testimony whereof I hereunto VaHX my signature.
